Character
Sunburst is the default Create model, and the one to open when an image has to behave like a designed object: a poster, a pack shot, a title card, or type set in the frame.
GPT Image 2.5 Sunburst follows a brief closely. Ask for a centered product, a specific aspect, a named lighting setup, or a line of type, and the frame tends to honor that structure instead of drifting into a generic scene. Resolution runs from 1K to 4K, so the same idea can stay a working study or become a large image.
Image to Image keeps the same controls: bring a reference, then describe the change in ordinary language.
Style
How GPT Image 2.5 Sunburst tends to see a picture.
Designed frames
Posters, covers, and campaign layouts stay organized. Hierarchy, margins, and a clear focal object are part of the look.
Readable type
Short lines of lettering can live inside the picture. It is worth checking spelling, especially on long phrases.
Commercial light
Studio light, soft product glow, and controlled color read cleanly. The finish leans polished rather than documentary.
Material clarity
Glass, metal, paper, and fabric keep their edges. Useful when the object itself is the subject.
In practice
The work this model is built to carry.
Campaign posters
A headline, a hero object, and a background that supports both.
Product images
Pack shots and product frames, with the object placed, the light named, and the surface specified.
Social visuals
Square and vertical frames that feel composed, not cropped by accident.
Reference edits
Keep a product or person recognizable and change the setting, palette, or crop.
Briefing
Write the brief the way an art director would mark up a frame. Name the subject, the crop, the surface, the light, and any words that must appear. If type matters, put the exact wording in quotes and say where it sits.
For an edit, describe what stays and what changes. A reference of the product plus a sentence about the new setting is usually clearer than a long mood essay.
Say the words exactly
If the image contains type, write the line as it should read and name its placement: top, centered, on the label.
Pick the resolution for the job
1K is enough to judge composition. Move to 2K or 4K when the image is the one you will keep.
Name the surface
For a pack shot, say what the object sits on and where the light comes from. A named surface and a named light keep the frame controlled.

GPT Image 2.5 Sunburst FAQ
GPT Image 2.5 Sunburst is an OpenAI image model and the default model in image.cooking’s Create workspace. It is built for images that behave like designed objects: posters, pack shots, title cards, and type set in the frame.
It runs from 1K to 4K for both Text to Image and Image to Image, so an idea can stay a working study or become a large image.
Short lines of lettering can sit in the frame. Write the exact words in quotes, say where they go, and check the spelling, especially on long phrases.
Both are GPT Image 2.5 models with the same controls: prompt, aspect ratio, 1K to 4K, and Image to Image. Sunburst is the default and the one to open for designed frames with layout and type. Flare pushes toward higher contrast, simpler shapes, and a more poster-like finish. The quickest way to compare them is to run the same prompt on both.
The price depends on the resolution, the number of outputs, and whether you use a reference image. At default settings, GPT Image 2.5 Sunburst costs 3 Credits. Create always shows the exact price before you start.
